If the digit of 0 is allowed, then:

1/(10*9*8)= 1/720

If it is not permitted, then:

1/(9*8*7)= 1/504

I hope this helps you!

Answer:

The probability that you will get a 3-digit combination correct is:

   1/720

Step-by-step explanation:

We are asked to find the probability that you will get a 3-digit combination correct if no digits in the combination can be repeated.

Now the favorable number of outcomes=1 (which is the correct combination)

Total number of outcomes=  10×9×8

(first place has 10 choices of digits from 0-9 ,second has 9 choices excluding the one at first place and third place has 8 choice)

                                           =720

Probability= number of favorable outcomes/total number of outcomes

                 =  1/720

MAVERICK [17]
Let
x-----> the measure of the angle formed by the wooden fence and grass

we know that
in a right triangle
tan x=opposite side angle x/adjacent side angle x
opposite side angle x=13 ft
adjacent side angle x=21 ft
so
tan x=13/21x=arc tan (13/21)-----> x=31.76°------> x=32°

the answer is
32 degrees
